Description

Background Art

[0002] Physics engines are used in games that need to simulate the physical movement of real objects. Physics engines calculate movement, rotation, and collision reactions by assigning real physical properties to object collision bodies, thereby enhancing the realism of the player's gaming experience.

[0003] However, when multiple collision bodies in the game forcibly squeeze and collide with each other, the squeezed virtual object will enter other models or fall below the ground. When the squeezed virtual object enters other models or falls below the ground, the collision blocking of the model is ineffective, causing the virtual object that falls into the model to be able to see through or directly attack the virtual object outside the model, while the virtual object outside the model cannot attack the virtual object inside the model, and the physics engine cannot adjust the position of the squeezed virtual object, reducing the fairness of the game and the player's gaming experience.

[0066] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as being limited to the examples set forth herein; on the contrary, these embodiments are provided so that the present invention will be more comprehensive and complete, and the concept of the example embodiments will be fully conveyed to those skilled in the art. The described features, structures, or characteristics may be combined in one or more embodiments in any suitable manner. In the following description, many specific details are provided to provide a full understanding of the embodiments of the present invention. However, those skilled in the art will appreciate that the technical solutions of the present invention may be practiced while omitting one or more of the specific details, or other methods, components, devices, steps, etc. may be adopted. In other cases, known technical solutions are not shown or described in detail to avoid obscuring various aspects of the present invention.

[0067] In addition, the accompanying drawings are only schematic illustrations of the present invention and are not necessarily drawn to scale. The same reference numerals in the figures represent the same or similar parts, and their repeated description will be omitted. Some of the block diagrams shown in the accompanying drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities can be implemented in software form, or implemented in one or more hardware modules or integrated circuits, or implemented in different networks and / or processor devices and / or microcontroller devices.

[0068] In games with physical movement of virtual objects, the physics engine calculates the movement, rotation, and collision reaction of virtual objects by assigning real physical properties to the virtual object collision body. While enjoying the realism and convenience brought by the physics engine, it also brings some problems. Figure 1 As shown in Figure 2, when a virtual object collides with a vehicle in the game, the virtual object will be squeezed under the ground; Figure 2 As shown, when the virtual object is between the door and the bus, when the virtual object opens and closes the door, the reference Figure 3 As shown, the virtual objects will be forced into the bus. After the virtual objects are squeezed into the bus, the collision blocking of the model is ineffective, causing the virtual objects inside the bus to be able to see through or shoot through the bus to hit the virtual objects outside, while the virtual objects outside the bus cannot see the attackers and cannot hit the attackers, which reduces the fairness of the game and the players' gaming experience.

[0069] In the collision of the physics engine, some can be modified through code or scenes. For example, to solve the problem of door jam collision in the game, the door in the game can be deleted or not allowed to open. However, the unfairness of the game caused by the player's operation is unavoidable.

[0070] In the related art, there are corresponding solutions to the problem of virtual objects falling below the ground. For example, in an aerial photography scene, the height accuracy of the scene terrain under the world coordinates is magnified, and the magnified accuracy is stored in the three RGB channels. The channels are saved in a large picture. When the picture is loaded in the game, the current position is proportionally converted to the position corresponding to the height map, the RGB value of the position in the height map is extracted and the height is calculated. When the current height is lower than the height map, it means that the virtual object has fallen under the ground of the model. At this time, the current height can be set to the height of the height map. However, the above method cannot solve the problem of virtual objects being squeezed into the inside of the model.

[0071] Based on one or more of the above problems, this exemplary embodiment first provides an information processing method, which can be run on a device terminal, which can include a desktop computer, a portable computer, a smart phone, a tablet computer, etc. Of course, those skilled in the art can also run the method of the present invention on other platforms as required, and this exemplary embodiment does not specifically limit this. Figure 4 As shown, the information processing method may include the following steps:

[0072] Step S410. Obtain the current position of the virtual object in the game and the last legal position relative to the current position;

[0073] Step S420: Perform ray detection on the current position and the last legal position, obtain a collision surface obtained by the ray detection, and determine whether the current position of the virtual object is an illegal position based on the collision surface;

[0074] Step S430: When it is determined that the current position of the virtual object is an illegal position, the current position of the virtual object is adjusted to the last legal position.

[0075] The above-mentioned information processing method obtains the current position of the virtual object in the game and the last legal position relative to the current position; performs ray detection on the current position and the last legal position, obtains the collision surface obtained by the ray detection, and judges whether the current position of the virtual object is an illegal position based on the collision surface; when it is determined that the current position of the virtual object is an illegal position, adjusts the current position of the virtual object to the last legal position; on the one hand, in the game, by obtaining the current position and the last legal position of the virtual object, and performing ray detection between the current position and the last legal position of the virtual object, the collision surface obtained by the ray detection is used to judge whether the current position of the virtual object is reasonable, and the efficiency of the position detection of the virtual object is improved by the ray detection; on the other hand, when the current position of the virtual object obtained by ray detection is an illegal position, the current position of the virtual object is adjusted, and the last legal position is used as the current position of the virtual object, thereby avoiding the problem in the related art that when the position of the virtual object is unreasonable, the collision blocking of the model is not effective and the physical engine cannot adjust the position of the virtual object squeezed into the model, thereby improving the fairness of the game and the game experience of the players.

[0076] Hereinafter, each step involved in the information processing method of the exemplary embodiment of the present disclosure is explained and illustrated in detail.

[0077] In step S410, the current position of the virtual object in the game and the last legal position relative to the current position are obtained.

[0078] The current position of the virtual object can be a legal position or an illegal position. In this example embodiment, the current position of the virtual object is not specifically limited. When the current position of the virtual object is inside the model or below the ground in the game scene, the current position of the virtual object is an illegal position; the last legal position is the legal position of the virtual object before it moves to the current position relative to the current position of the virtual object.

[0079] In step S420, ray detection is performed on the current position and the previous legal position to obtain a collision surface obtained by the ray detection, and based on the collision surface, it is determined whether the current position of the virtual object is an illegal position.

[0080] In this example embodiment, ray detection is that the physics engine draws a ray between the current position and the last legal position of the virtual object based on the two points, and returns collision information of the ray hitting the collision body. The collision information may include the collision body, the coordinates of the collision point, the normal of the collision surface, etc., wherein the normal of the collision surface is a vector perpendicular to the collision triangle.

[0081] In this example embodiment, the principle of culling collision faces inside the model is used to determine whether the current position of the virtual object is legal. Face culling is when drawing a model. In order to reduce rendering consumption, invisible model faces will be discarded and not drawn. For example, the faces inside the model, each model face is composed of three vertices. In the rendering process, the order in which the vertices are used to draw the triangle faces (clockwise or counterclockwise) will be used to determine whether a triangle is a forward triangle or a back triangle. By default, triangles defined by counterclockwise vertices will be processed as forward triangles. Face culling also exists in collision bodies. The collision in this example embodiment is a scene collision, which is a static collision. Each collision body has a collision group. When a collision occurs between collision bodies, the value of the collision group of the collision body is bitwise operated to determine whether the collision is a static collision. Other methods can also be used to determine whether the collision is a static collision, which is not specifically limited in this example embodiment.

[0082] refer to Figure 5 As shown, performing ray detection on the current position and the previous legal position to obtain a collision surface obtained by the ray detection may include step S510 and step S520:

[0083] Step S510. Based on the current position of the virtual object, a ray is emitted to the last legal position to perform a first ray detection;

[0084] Step S520: Based on the first ray detection, a collision surface between the current position of the virtual object and the previous legal position is obtained, wherein the collision surface is a positive collision surface or a negative collision surface.

[0085] In the following, step S510 and step S520 will be further explained and illustrated. Specifically, after the current position and the last legal position of the virtual object are obtained, the current position of the virtual object can be used as the starting point and the last legal position as the end point, a ray can be emitted, and a first ray detection can be performed. Based on the first ray detection, the collision surface between the current position and the last legal position of the virtual object can be obtained; wherein the collision surface can be a positive collision surface or a negative collision surface, and the collision surface is not specifically limited in this example embodiment.

[0086] In this example embodiment, reference Figure 6 As shown, after obtaining the collision surface between the current position of the virtual object and the previous legal position, the information processing method may further include step S610 and step S620:

[0087] Step S610. Acquire frontal collision information corresponding to the frontal collision surface and rearward collision information corresponding to the rearward collision surface;

[0088] Step S620: Perform collision screening according to the frontal collision information and the rearward collision information.

[0089] In the following, step S610 and step S620 will be further explained and illustrated. Specifically, first, after the collision surface between the current position and the previous legal position of the virtual object is obtained through the first ray detection, the detected collision surface is judged to determine whether the collision surface is a positive collision surface or a negative collision surface. When the collision surface is a positive collision surface, all positive collision information corresponding to the positive collision surface is obtained; when the collision surface is a negative collision surface, all negative collision information corresponding to the negative collision surface is obtained. After the positive collision information and the negative collision information are obtained, collision screening can be performed according to the positive collision information and the negative collision information.

[0090] For further reference, Figure 7 As shown, performing collision screening according to the frontal collision information and the rearward collision information may include step S710 and step S720:

[0091] Step S710: Obtaining the collision type of the collision according to the frontal collision information and the rearward collision information;

[0092] Step S720: According to the collision type, determine a first collision among the collisions that does not need to be detected, and perform collision screening on the first collision.

[0093] In the following, step S710 and step S720 will be further explained and illustrated. Specifically, after obtaining the frontal collision information and the rear collision information, the collision type of each collision can be obtained according to the collision grouping of the collision bodies included in the frontal collision information and the rear collision information; then, according to the collision type, it is determined whether the collision is a first collision that does not need to be detected. When the collision is a first collision that does not need to be detected, that is, when the collision is an invalid collision, the collision is eliminated. Among them, the first collision can be a road collision or a water collision. In this example embodiment, the collision type included in the first collision is not specifically limited, and the first collision can be determined according to the actual scene needs.

[0094] In this example embodiment, after obtaining the collision surface in the first ray detection and eliminating the invalid collisions in the collision, the current position of the virtual object can be judged according to the collision surface of the valid collision, referring to Figure 8 As shown, judging whether the current position of the virtual object is an illegal position may include steps S810 to S830:

[0095] Step S810: Determine whether the positive collision surface corresponds to the negative collision surface and whether the first collision surface among the collision surfaces is a positive collision surface;

[0096] Step S820: when the positive collision surface corresponds to the negative collision surface and the first collision surface is a positive collision surface, the current position of the virtual object is a legal position;

[0097] Step S830: When the positive collision surface does not correspond to the negative collision surface or the first collision surface is not a positive collision surface, the current position of the virtual object may be an illegal position.

[0098] The following will further explain and illustrate steps S810 to S830. Fig. 9 As shown, when the ray passes through the two collision bodies from the leftmost end of the first collision body, the positive collision surface 901 and the reverse collision surface 902 in the first collision body are corresponding, and the positive collision surface 903 and the reverse collision surface 904 in the second collision body are corresponding; refer to Fig.10As shown, the positive collision surface 1001 corresponds to the reverse collision surface 1002, and the collision surface 1003 is a redundant collision surface. When there is an extra reverse collision surface 1003 in the collision, according to the principle of eliminating the internal collision surface of the model, it can be determined that the starting point of the ray is located inside the first collision body; therefore, when judging the current position of the virtual object, it can be judged whether the positive collision surface in the collision corresponds to the reverse collision surface and whether the first collision surface is the positive collision surface; when the positive collision and the reverse collision are one-to-one corresponding and the first collision surface is the positive collision surface, it can be determined that the current position of the virtual object is a legal position, that is, the current position of the virtual object is not in the model or below the ground; when the positive collision surface does not correspond to the reverse collision surface and or the first collision surface is not the positive collision surface, it can be considered that the current position of the virtual object may be an illegal position.

[0099] In this example embodiment, a ray is emitted from the current position of the virtual object to the previous legal position for the first ray detection. When the current position of the virtual object is a legal position, a pair of positive collision surfaces and negative collision surfaces are obtained through the first ray detection, and the first collision surface among the obtained collision surfaces is definitely a positive collision surface. When the positive collision surface and the negative collision surface obtained through the first ray detection are not paired or the first collision surface is not a positive collision surface, it may be because some collision bodies themselves are single-sided and not closed collision bodies. Therefore, it is necessary to further judge the virtual object whose current position may be an illegal position.

[0100] refer to Fig.11 As shown, when the current position of the virtual object may be an illegal position, the information processing method may further include steps S1110 to S1130:

[0101] Step S1110. According to the collision type of the collision, determine whether the collision is a preset first type collision;

[0102] Step S1120: when it is determined that the collision is a preset first type of collision, the current position of the virtual object is an illegal position;

[0103] Step S1130: When it is determined that the collision is not a preset first type collision, reverse detection is performed on the position of the virtual object.

[0104] Below, step S1110-step S1130 will be further explained and illustrated. Specifically, when it is determined that the current position of the virtual object may be an illegal position, further judgment can be made through the collision type of the collision in the first ray detection. First, the collision type of the collision is obtained, and it is determined whether the obtained collision type is a preset first type collision. When the collision type is a preset first type collision, the current position of the virtual object is determined to be an illegal position; wherein, the preset first type collision can be a reverse terrain collision or other collision. In this example embodiment, the preset first type collision is not specifically limited. When the current position of the virtual object is below the ground, when a ray is sent to the upper legal position based on the current position of the virtual object for the first ray detection, the collision obtained by the first ray detection is a reverse terrain collision. In addition, when it is determined that the collision obtained by the first ray detection is not a preset first type collision, the current position of the virtual object can be reversely detected.

[0105] refer to Fig.12 As shown, when it is determined that the collision is not the preset first type collision, reverse detection is performed on the current position of the virtual object, which may include steps S1210 to S1230:

[0106] Step S1210. Based on the current position of the virtual object, a ray is emitted in the opposite direction of the line connecting the current position and the last legal position to perform a second ray detection;

[0107] Step S1220. Obtain the first collision surface in the second ray detection. When it is determined that there is a counter-collision surface in the collision surface of the second ray detection, and the counter-collision surface is a collision surface in the collision body corresponding to the unpaired counter-collision surface in the first ray detection, the current position of the virtual object is an illegal position.

[0108] In the following, step S1210 to step S1230 will be further explained and illustrated. Specifically, first, determine the direction of the line connecting the current position of the virtual object and the last legal position, then, based on the current position of the virtual object, emit a ray in the opposite direction of the line connecting the current position of the virtual object and the last legal position, that is, take the current position of the virtual object as the starting point, send a ray of a preset length in the opposite direction of the line connecting the current position of the virtual object and the last legal position, and perform a second ray detection, that is, in the second ray detection, the starting point of the ray is the current position of the virtual object. In this example embodiment, the length of the ray is not specifically limited, and those skilled in the art can determine the length of the ray emitted based on the current position of the virtual object as needed; then, obtain the collision surface in the second ray detection, and it is necessary to determine whether there is an anti-collision surface in the collision surface obtained by the second ray detection. When there is an anti-collision surface in the second ray detection, and the anti-collision surface is a collision surface in the collision body corresponding to the unpaired anti-collision surface in the first ray detection, it can be determined that the current position of the virtual object is an illegal position; otherwise, the current position of the virtual object is a legal position.

[0109] For example, in this exemplary embodiment, there are two collision bodies interlaced, refer to Fig.13 As shown, when there is an interlacing between collision body A and collision body B, in the first ray detection 1301, the reverse collision surface 1302 is an unpaired collision surface. Therefore, it is necessary to perform a reverse detection on the current position of the virtual object. When performing the reverse detection, the positive collision surface 1304, the reverse collision surface 1305 and the reverse collision surface 1306 can be obtained through the second ray detection 1303, wherein the positive collision surface 1304 corresponds to the reverse collision surface 1306, indicating that the current position of the virtual object is not in the collision body B, and the reverse collision surface 1305 is the surface in the collision body A corresponding to the unpaired reverse collision surface 1302 in the first ray detection, that is, the current position of the virtual object is in the collision body A, and the current position of the virtual object is an illegal position. Therefore, when a second ray detection is performed on the current position of the virtual object, it is necessary to determine whether there is an anti-collision surface in the collision surface of the second ray detection, and whether the anti-collision surface is a surface in a collision body corresponding to the unpaired anti-collision surface in the first ray detection. If so, the current position of the virtual object is an illegal position; otherwise, the current position of the virtual object is a legal position.

[0110] In this example embodiment, reference Fig.14 As shown, judging whether the collision surface is a positive collision surface or a negative collision surface may include steps S1410 to S1430:

[0111] Step S1410. Acquire collision information obtained through the first ray detection;

[0112] Step S1420. Obtain the reverse vector of the ray in the first ray detection, perform dot multiplication on the reverse vector and the normal vector of the collision surface in the collision information, and obtain a dot multiplication result;

[0113] Step S1430: Determine whether the collision surface is a positive collision surface or a negative collision surface according to the dot product result.

[0114] In the following, step S1410-step S1430 will be further explained and illustrated. Specifically, first, collision information obtained based on the first ray detection is obtained, wherein the collision information may include a collision body, a collision point coordinate, and a normal of a collision surface, etc. In this exemplary embodiment, the collision information is not specifically limited. After the collision information is obtained, a reverse vector pointing from the last legal position of the virtual object to the current position of the virtual object in the first ray detection, which is opposite to the ray direction, can also be obtained; then, the angle between the reverse vector and the normal of the collision surface in the collision information is obtained, and the reverse vector, the normal vector of the collision surface, and the angle between the reverse vector and the normal of the collision surface in the collision information are multiplied to obtain the dot product result. When the dot product result is less than 0, it indicates that the angle between the reverse vector and the normal of the collision surface in the collision information is greater than 90 degrees, that is, the current position of the virtual object is behind the normal of the collision surface, and the collision surface is a reverse collision surface; when the dot product result is greater than 0, the collision surface is a positive collision surface.

[0115] For example, refer to Fig.15 As shown in the figure, position A is the last legal position of the virtual object, and position B is the current position of the virtual object. When performing ray detection, a ray needs to be emitted from position B to position A. The physics engine will return the collision information of the ray, including the collision point P and the normal N of the collision surface. When the angle between the reverse direction AB of the ray and the normal N is θ, according to the vector dot multiplication formula AB*N=|AB|*|N|*cosθ and the cosine trigonometric function, Figure 1 6 In the cosine trigonometric curve diagram, when the included angle θ∈(90, 180), cosθ<0, then |AB|*|N|*cosθ<0, that is, when the dot product result is less than 0, θ>90, indicating that the current position of the virtual object is behind the normal N, that is, behind the collision surface, and the collision surface is a reverse collision surface; when the dot product result is greater than 0, it indicates that the collision surface is a positive collision surface.

[0116] In step S430, when it is determined that the current position of the virtual object is unreasonable, the current position of the virtual object is adjusted to the last legal position.

[0117] In this example embodiment, when the current position of the virtual object is detected and it is found that the current position of the virtual object is an illegal position, the current position of the virtual object can be adjusted to the last legal position of the virtual object, that is, the virtual object is pulled back to the last legal position; when it is determined that the current position of the virtual object is a legal position, the last legal position is updated as the current position of the virtual object, and the current position is synchronized to the server.

[0118] For example, refer to Fig.17 According to the flowchart shown, after entering the game scene, first, the coordinates of the last legal position of the virtual object are obtained from the server; then, the current position of the virtual object is detected to determine whether the current position of the virtual object is legal. When the current position of the virtual object is legal, the last legal position of the virtual object is updated to the current position of the virtual object, and the current position of the virtual object is synchronized to the server, and the current position of the virtual object is detected at preset intervals; when the current position of the virtual object is illegal, the current position of the virtual object is adjusted to the last legal position of the virtual object, that is, the virtual object is pulled back to the last legal position, and the current position of the virtual object is detected at preset intervals.

[0119] The information processing method provided by the exemplary embodiments of the present disclosure has at least the following advantages: on the one hand, in the game, by obtaining the current position and the last legal position of the virtual object, and performing ray detection between the current position and the last legal position of the virtual object, whether the current position of the virtual object is reasonable is judged by the collision surface obtained by the ray detection, and the efficiency of the position detection of the virtual object is improved by the ray detection; on the other hand, when the current position of the virtual object obtained by the ray detection is an illegal position, the current position of the virtual object is adjusted, and the last legal position is used as the current position of the virtual object, thereby avoiding the problem in the related art that when the position of the virtual object is unreasonable, the collision blocking of the model is not effective and the physical engine cannot adjust the position of the virtual object squeezed into the inside of the model, thereby improving the fairness of the game and the game experience of the player; on the other hand, when the first ray detection is performed on the virtual object, if it is detected that the current position of the virtual object may be an illegal position, the current position of the virtual object is reversely detected again, thereby ensuring the integrity of the collision detection and improving the accuracy of the current position detection of the virtual object.
